Amiens, FranceAges 18 years+ - NCT05946174Recruiting
Personalized frailty program for older people with heart frailty
This trial aims to adjust frailty-support activities for people who are physically vulnerable because of heart problems. It may help by creating a plan tailored to your needs, while carefully checking health issues that could make participation unsafe.
SingaporeAges 21–100 - NCT05946772RecruitingPhase 2
Cyclosporine for Takotsubo heart weakness in the first day
This trial studies whether cyclosporine, an immune-related medicine, can improve outcomes in Takotsubo syndrome (a temporary heart muscle problem). It aims to start treatment very soon after a heart catheter test to help the heart recover.
Bad NauheimAges 18 years+ - NCT05946850Recruiting
Caudal pain block study for adults with chronic pain
This trial looks at giving a specific pain procedure called caudal analgesia to adults with long-term (chronic) pain. It may help reduce pain after the procedure, and it will compare results for people who can safely receive it.
Surrey, British ColumbiaAges 20–99 - NCT05947136Recruiting
PASCA program study after stem cell transplant for myeloma
This study checks whether the PASCA health program helps reduce complications in people with multiple myeloma after their first stem cell transplant. It may help by improving how patients manage side effects during recovery and ongoing treatment.
ÉpagnyAges 18–70 - NCT05948566RecruitingPhase 2
Improving response to stroke treatment with an antibody drug
This Phase 2 trial tests an antibody treatment (TS23) given to people with a suspected acute ischemic stroke to improve how well they respond to stroke care. You may qualify if your stroke scan shows the right pattern of injured brain tissue and if the study drug can be given within a short time window after symptoms start.
Birmingham, AlabamaAges 18 years+ - NCT05951101Recruiting
Device to close an irregular heartbeat heart pocket safely
This trial tests the Zenith system, a device that seals off a heart area called the left atrial appendage to reduce stroke risk in people with atrial fibrillation (AF). You may be eligible if you have AF and a doctor recommends LAA closure, and you can return for follow-up scans and visits.
Parkville, VictoriaAges 18 years+ - NCT05951517Recruiting
Mycophenolate for stubborn stomach Purpura (HSP) in children
This trial looks at whether mycophenolate mofetil can help children ages 3–18 who have Henoch-Schönlein purpura affecting the gut that does not improve with steroid treatment. It may help reduce serious stomach symptoms like severe belly pain, bleeding, or bowel problems.
Guangzhou, GuangdongAges 3–18 - NCT05954741Recruiting
Rehab program to improve thinking in recent vascular memory problems
This trial tests a structured, multi-part rehabilitation program to help people with early dementia symptoms from vascular or mixed causes. If you qualify, you may be offered the rehab program and compared with another approach to see if thinking and daily function improve.
Montescano, PaviaAges 65–80 - NCT05955326RecruitingPhase 4
Testing a stroke drug to improve recovery after ischemic stroke
This trial tests whether sovateltide is safe and can improve recovery in people with an acute ischemic stroke. It focuses on patients who start the study drug within 24 hours of symptom onset and do not have bleeding in the brain.
Guntur, Andhra PradeshAges 18–78 - NCT05955014Recruiting
Study collects data from people with von Hippel-Lindau disease
This study is for people with von Hippel-Lindau (vHL) disease to collect information for research. It may help researchers better understand the condition and how to care for people with it.
Houston, TexasAges 18 years+ - NCT05955339Recruiting
Using visit recordings and open notes to improve care experience
This study tests two ways of sharing what happened at clinic visits—recording visits and using an “open notes” patient portal—to help older adults manage long-term health conditions with a better experience. It’s likely to help if you have multiple chronic conditions and can use email or a patient portal.
Manchester, New HampshireAges 18 years+ - NCT05955456Recruiting
Check ways to spot early heart failure
This study looks for people who may be developing heart failure early, using heart imaging and related checks. If you fit the risk pattern, the results may help find heart failure sooner in similar people.
Manchester, Greater ManchesterAges 50 years+ - NCT05955365RecruitingPhase 4
Single anticoagulant blood thinner after stent in atrial fibrillation
This trial tests whether taking a single “P2Y12 inhibitor” blood thinner (instead of multiple medicines) is safe and effective after you get a coronary stent. It’s for people with atrial fibrillation who need long-term blood thinning and have recently had a successful stent procedure.
